EFI bracket is no good as it puts the compressor where your steerig box is.

Just get a 253/308 V8 bracket and pulley off a HQ-HZ.

Note, if you can get the WHOLE car (6cyl HZ), or get the whole firewall cut with all A/C on it. Get the LHS inner guard too. That way you can leave it all intact and swap it over a bit at a time. You need to drill 6 x holes in the body: 1 x 32mm for the harness, 3 x overlapping 16mm for the heater hoses (there are guides for these on a non-A/C car) and 2 x small screw holes for the A/C air supply and blanking plate under the dash. There is also holes needed in the radiator support for the condensor hoses (overlapping holes, guides are here too to show you where to drill).
